Recommended (free): PHP7
1. First download the PHP7 installation package and use wget http:// am1.php.net/distributions/php-7.2.0.tar.bz2, or download it directly, and then ftp to the linux server
2. Unzip the compressed package, tar –xjf php-7.0.2.tar.bz2
3. Enter the folder, cd php-7.0.2, and install the necessary dependent tools.
yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel curl curl-devel openssl openssl-devel
The main purpose here is to upgrade, which is usually installed in php5, so this step can be omitted
4. Install several dependencies (must be installed, otherwise the libphp7.so file used by apache cannot be generated later)
yum -y install perl yum –y install perl-develyum -y install httpd-develfind /usr -name apxs 取得所用路径,后面编译时用到。
5. Prepare for compilation
./configure --prefix=/usr/local/php7 --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-xmlrpc --with-xsl --with-zlib --enable-fpm --enable-bcmath -enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-xml --enable-zip --enable-pcntl --with-curl --with-fpm-user=nginx --enable-ftp --enable-session --enable-xml --with-apxs2=/usr/bin/apxs
**Note: The –enable-gd-native-ttf does not need to be installed. It is used for graphics processing. If necessary, it can be installed in an extended form later
–with-apxs2= Change the path behind /usr/bin/apxs to the path obtained in step 4
–prefix=/usr/local/php7 Install it separately in the php7 folder to avoid conflict with php5**
6. Compile
make
This step is prone to many problems,
If you encounter, for example: undefine. . . .
/ext/cli./php …
Openssl
and other errors, and make sure that the relevant modules are installed, generally clear the previous compilation, delete the relevant files and recompile
make clean rm –rf /usr/local/php7
Generally the problem can be solved.
For other errors, please refer to this blog:

The key is to solve it yourself. Since there are too many Linux distributions and the environment configuration of each server is different, you will encounter many strange problems.
7. Install
Make install
8. Prepare the configuration file
cp php.ini-developement /etc/php.ini //根据实际情况,可以使用production或者development默认配置cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.confcp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
9. Need to modify the apache configuration file
Vi /etc/httpd/conf/httpd.conf Find LoadModule php7_module modules/libphp7.so, if not added manually,
Comment out LoadModule php5_module modules/libphp5.so
cp /etc/httpd/conf.d/php.conf /etc/httpd/conf.d /php.conf_5
Vi /etc/httpd/conf.d/php.conf
Change to the following: (Comment out the ones related to php5 and change to php7 related modules)
<IfModule prefork.c> LoadModule php7_module modules/libphp7.so</IfModule><Files ".user.ini"> <IfModule mod_authz_core.c> Require all denied </IfModule> <IfModule !mod_authz_core.c> Order allow,deny Deny from all Satisfy All</IfModule></Files>DirectoryIndex index.php# mod_php options<IfModule mod_php7.c> <FilesMatch \.php$> SetHandler application/x-httpd-php</FilesMatch> php_value session.save_handler "files" php_value session.save_path "/var/lib/php/session" php_value soap.wsdl_cache_dir "/var/lib/php/wsdlcache"</IfModule>
10. Restart apache server
service httpd restart
